BACKGROUND

It is known in the art that belts refer to the belt for girdling the waist. The material of belts may be leather. Belts are usually composed of buckle and belt body. One end of the belt body fixedly connects with the buckle. The other end of the belt body can be connected to the buckle during use. The common buckles include pin buckle, plate buckle, automatic buckle, clip, etc. Although there are a lot of kinds of buckles, the length of all belts cannot be changed after a user ties and fixes the belt on the waist. The waistline, however, will vary as a result of drinking, eating, or changing posture, such as standing up or sitting down. Apparently, the length of known belts cannot be automatically adjusted. It is not practical for frequently manual adjustment of the length. In addition, the waistline is always manually measured in the art. Manual measurement for waistline is not accurate and troublesome. Therefore, it is desired to develop a belt that can measures the waistline on a real-time basis, thereby automatically adjusting the length of the belt.

The waistline-measuring device 11, the length-adjusting device 12, and the belt-body-fastening device 13, all include a hollow housing with a cuboid shape. The housings are connected in turn by hinges 112. The waistline-measuring device 11, the length-adjusting device 12, and the belt-body-fastening device 13 are provided with a first groove 111, a second groove 121, and a third groove 131 that the belt body passes through, respectively.

The waistline-measuring device 11 includes a roller 113, a rotary encoder 114, and a counter 115. The roller 113 is positioned in the inner cavity of the waistline-measuring device 11. A portion of the roller 113 extends into the first groove 111 and contacts with the belt body 2. The rotary encoder 114 electrically connects with the roller 113. The rotary encoder 114 electrically connects with the counter 115. The movement of belt body 2 drives the rotation of the roller 113. The rotatory encoder 114 and the counter 115 cooperate to detect the length of the belt body 2 that passes through the first groove 111.

The belt-body-fastening device 13 is provided with an indentation 1321. One end of the belt body 2 is inserted into the indentation 1321 and fixedly connected by an L-shaped gusset plate 132 hinged to the belt-body-fastening device 13. The other end of the belt body2 is provided with a slot 21 and an adjusting buckle 22. The adjusting buckle 22 is made of two pieces of C-shaped plates 221.

The platen 128 extends into the second groove 121 and contacts with the slot 21. The electromagnetic array 122 is arranged by a plurality of second electromagnets 1221 in the direction of the movement of the belt body 2.

The gyroscope 124 and the accelerometer 126 are responsible for tracking the user's motion data. The pressure sensor 116 is responsible for the detection of the force applied on the belt. Based on the principle of the interaction force, the pressure detected by the pressure sensor 116 is equal to the tension applied on the belt.

The combination of the platen 128 and the magnet 129 serves to bring one end of the platen 128 into contact with the slot 21 to lock the belt body 2 and the first electromagnet 120 is actuated to lift the platen 128 to release the belt body 2.

The electromagnet array 122 is comprised of a number of second electromagnets 1221. One or more of the second electromagnets 1221 is driven to move the adjusting buckle 22 to adjust the length of the belt until the pressure detected by the pressure sensor 116 is equal to or close to the set value. Thereafter, the one or more of the second electromagnets 1221 stops being driven, and the combination of the platen 128 and the magnet 129 locks the movement of the belt body 2.

The micro controller 123 is used to collect and process the data of the pressure sensor 116 and the counter 115, control the electromagnetic array 122, and the first electromagnet 120, and control the communication of the wireless transceiver 125 with the external device.
